In XG, domain user authentication does not work

Hello,

I installed an XG 105 and integrated it with Active Directory, on the domain controller I set up STAS and it is working, I created a user named xg @ domain and I put it in the Domain Admins group.
This user starts the STAS service on the domain controller and is also used in XG, the groups were imported normally, in the configuration and DNS, I put the IP of the two domain controllers as primary and secondary.
But when I create the firewall rules to authenticate the users, it does not work, the users do not appear in live users, so I'm using firewall rules by machines, without the use of domain user authentication, because it does not work.

What can I have forgotten?

Thanks !
